As I said, a worn flex disc causes a clunk during shifting. Once the shift is completed and driveshaft speed matches engine speed, the slop in the worn flex disc is taken up,"clunk," and the flex disc does not shudder or vibrate after that, IME.
Balancing the driveshaft sounds like a waste of $. . .not likely to be an issue at low speed in stop+go traffic.
If you are going to spend $ on the driveshaft, you should just go ahead an get a rebuilt one because the U-joints will eventually wear out and are not serviceable(can't be greased or replaced), so you will need to replace the driveshaft at some point anyhow if you keep the car for a long time.
Rebuilt driveshafts usually include a new center support bearing(CSB). A worn CSB can be a source of vibration in the driveline, but the correlation with ambient temperature sounds more like a clutch thing to me. Don't be surprised if you spend $500 on your driveshaft and your problem persists.
If you are determined to do the driveshaft now,
here are some driveshaft places:
